Colour Mixing: Easy Science Experiments for Kids

Here are interactive colour mixing science experiments, in which you can use any medium from paint to food dye to explore the magical world of colors.

Teach your toddler or preschooler about the effects and results of mixing different colours together to form new ones.

Exploring and experimenting with color mixing can stimulate children's cognitive thinking, creativity and imagination all while having fun and producing unpredictable and interesting results.

Color Mixing Experiments

Try an experiment below to begin exploring and discovering the magical world of colours with your child.

Paint Experiments

There are 3 primary colours - red, blue and yellow.

No combination of other shades can create primary colors, however all primaries can be mixed in various combinations to make more hues.

Kids at this age are usually only interested in mixing primary colors to create secondary ones, and mixing secondary tints to create tertiary.

Basic Primary Color Combinations:
Red + Blue = Purple
Blue + Yellow = Green
Yellow + Red = Orange

Have at the look of an example colour wheel below:

Basic Primary Colour Mixing

What You Need:

  • Blue, Red and Yellow Paint
  • Small yoghurt or other containers
  • Brushes (or fingers)
  • Paper - A3 is ideal

What To Do:

Give your child 2 colours at a time to experiment with.
Let them put a little of the first one onto the paper.
Then let them add the second one to the first and show them how to mix the paints together to create a new colour.
On another part of the same sheet of paper, let them experiment with another combination and then the last combination.
Once they have created 3 new colors let them mix those together so they can observe what other shades they can make.
